Optel manufactures digital ultraviolet [uv] intensity meters. These digital ultraviolet intensity meters are extremely useful in measuring the intensity of uv light and black light. The ultraviolet rays have to be monitored and kept under control, as these are very harmful and so uv standard meters should be used for measuring the intensity. The company provides ultraviolet intensity devices for intensity measurement in a wide range including standard uv meter for measuring 365 mm intensity of the ultra-violet rays, special uv-meter to measure intensity uva [365 mm], uvb [312 nm] and uvc [254 nm]. These ultraviolet intensity meters find applications in measuring ultra-violet intensity from light source like star-sun, ultraviolet light in uv-eprom erasers erasing system, curing systems, backlight in ndt inspections, medical/clinical application, germicidal and sterilizing lights.
